' Therefore; the principal object and effect of my; invention is to provide an envelop with means so constructed and arranged that it imaybe utilized to seclu'de any such original key, fromthetime of its manufacture until its delivery to the lessee,

- Itis the usual practice, and is desirable, to. store ,such keys in racks-comprising compartments but slightly larger than the-shanks of two similar keys which are-furnished with each'lockfor theuse of the lessee. Therefore, it is a'further object and effect of my inventionito' provide an envelop which may be used to seelude 'suclra pair .o'fkeys'to'gether and in such manner asnOt to interfere with the storage. and removal of such key packages with respect to such racks. Y g

In the "preferred form of my invention hereinafter described, such an envelop in-' cludesa: seamless tube of flexible m'aterial,;fit-

' ting over the shank portions of the keys which are provided with the bittingnotches for the,

locktumblers; said tube being slit or slotted longitudinally" atone end, so thatopposite:

sidewallsthereof may extend upon opposite faces-of thelkey handles jsuch extensions being perforated inre'gistry with a hole in the handle of the'l (ey,.thus adapted to beachnect'ed by a fastening member extending through the key and secured upon: opposite sidesof the'envelop. Such a fastening mem ber-may be an eyelet, or other'form of rivet.

, Although: suchjsecluding means isin no i sense burglar-proof, it is of; such character tubular form.

I and II; thepair of keys are precisely alike, each having a shankl with. bittings 2 along one edge jthereofand a ,han- .dle 3 atone endthereof, with an opening 4 therethroughr Said keys are convenientlyplaced with their bittings extendin'g'in oppo site,directionsv and" with their shanks fitted in the envelop 6,. Whieh'is'a seamless tube of seve'red at suitable intervals as indicatedf However, as indicated in F gs. III, IV," and metal, celluloid or other suitable material,

preferably of a flexible nature. Said tube- 6 is slotted so as to remove its opposite edge walls, as indicatedat 7, and leave its opposite side walls extend upon opposite faces of the key handles; such extensions, indicated at 8, being perforated at 9 in registry with the holes in the handles of the keys, to receive the fastening ,niember 10 whichiis] an eyelet.

having flanges 11 and 12 extending upon opposite sides of the envelop which is thus se curel y fastened in suchrelation with the keys moval of said envelop andrelease of theke'ysQ Such envelops 6 as shown in Figs. I and 11, may be formed of aseamless rectangular tube of thin brass, copper, aluminum, celluloid or vulcanized fibre 13,-'as indicated :in VII; said tube being, punched and V, an envel'qpl L may beformed of primarily plane blanks the to the eyelet 10.

Of course, such fastening members 10 and 17 are merely tubular rivetsfand it'is to be understood that solid rivets may be employed in lieuthereoff However, instead of form-' ing tlie' fastening means asa "separate piece subsequently connected with the' envelop, I- may form VIII, pressed to such form th-atthey extend in the holesetin the keys into contact with each other and may thenvbe'sp ot 'welded tosidewalls of the envelop through the; keys and prevent removal of the latter, from the envelop untilsuch fastening means. is dis rupted. 4 I

' However, the form of niy invention wherein the fasten ng member is'distin'ct and separable from the envelop structure, is advantageous in that such a fastening member having it"sfends "outwardly flanged to larger di; ameter than the perforations 1n the keyham,

dles through which it extends, may bensed to retain the pair ofkeysin 'co upledrelation,

after the envelop is removed, anduntil such J fastenlng member isdisrupted andrem'ovedj 7 Therefore, I do not desire; to limit myself to the precise details of constructiei'n; 'arrangeinent or method of manufacture herein set lfbrth asit ifsfobvi'ous that various modific'a't i ons may be' made therein withoutdeparting from' the essential features of inl vention, ias' 'defined in the appended claims.
